'Evil Spirit' in the Bible

Now the Spirit of the LORD departed from Saul, and an evil spirit from the LORD troubled him.

Saul's servants said to him, "See now, an evil spirit from God troubles you.

Let our lord now command your servants who are before you, to seek out a man who is a skillful player on the harp. It shall happen, when the evil spirit from God is on you, that he shall play with his hand, and you shall be well."

It happened, when the spirit from God was on Saul, that David took the harp, and played with his hand: so Saul was refreshed, and was well, and the evil spirit departed from him.

It happened on the next day, that an evil spirit from God came mightily on Saul, and he prophesied in the midst of the house. David played with his hand, as he did day by day. Saul had his spear in his hand;

An evil spirit from the LORD was on Saul, as he sat in his house with his spear in his hand; and David was playing with his hand.
